Advice on acne

[archubbycub]

So I'm almost 35 years old and I still have acne problems. I had hoped it would clear up by now but apparently it's stubborn. It's not so much on my face, though I do get the occasional breakout on my forehead, as it is over my body, especially my back and my thighs. I know I could see a dermatologist but that's a little out of my price range at this time. And I know a lot of it has to do with diet as well, and I'm working on eating healthier, but is there any tips or tricks you all could give me to help clear this up?
